COOLING DEVICE FOR COMPRESSORS AND CONDENSERS.

Application filed December 2, 1925. Serial No; 72,725.

This. invention relates primarily `to a cooling device and moreparticularly to av ,cooling device associated with a refrigerant-- ingunit in which a motor-operated fan is 6 mounted upon a base sectioncontainipg a condenser, between the pipes of which airis drawn by meansof the fan to not only cool the condenser but to direct currents of airagainst the compressor of the refrigerating 10 unit to cool the same.

p w It is an object of this invention to provide asimplied form ofcooling device for both the compressor and the radiator type condenserof a refrigerator unit.

It is also an object of this invention to provide a refrigerating unitwith a cooling device adapted to be mounted between the compressor anddriving motor of a refrigerating unit to, draw air upwardly through thecondenser-containing base of the unit to cause the air to rst cool thecondenser and then be directed against the compressor to cool the same.

It is an important obj ect of this invention to provide a refrigeratingunit wherein a cooling device operated from the motor of the unit isadapted to act as a means for cooling both the condenser and thecompressor by drawing air through the condenser-enclosing base into ahood for discharge against the compressor.

Other and further important objects of this invention will be apparentfrom the disclosures in the specification and accompanying drawings.Y t

rlthe invention (in a preferred form) is iilustrated in the accompanyingdrawings.

and hereinafter more fully described.

0n the drawings: to

ating unit partly broken away and equipped with an improved coolingdevice embodying the principles of this invention.

Figure 2 is a transverse vertical section taken on line lil-H of Figurel.

As shown on the drawings: The reference numeral- 1 indicates a pedestalor base of a refrigerating unit, said base being supported on legs -2and open atV -the pipe 11 leading to the radiator type con- Figure 1 isa side elevation of a refriger-v ures 1 aiid 2 one end portion of thetop 55 wall of lthe base lis provided with a lon .--1 tudinally disposedpocket or trough 4,.t e inner end of which is open and communi-v cateswith the opening 3 in the top wall of the base. Mounted upon the middleportion of the base 1 is a hood or dome 5 having an outlet opening ormouth 6 vformed in the front wall' thereof. Also mounted upon the top ofthe base lis a driving motor "6', the shaft 7 of which projects into thehood 5. Mounted on the motor shaft 7 within the "hd 5 is a fan wheel 8.Rigidly mounted upon the top of the opposite end of the base 1 is acompressor 9 which is positioned adjacent the open end of the hood 5.Mounted within the Lbase 1 is a radiator type condenser 10 which isconnected with the compreSsor 9 by means of a pipe 11. A baiie wall 12is mounted within the base 1 above the lower end of the inclinedcondenser 10. The operation is as follows: v The refrigcrating unit isclearly illustrated in Figure 1 and is adapted to be driven by the motor6', the shaft 7 of which projects through the hood 5 and is connectedwith the compressor 9 to drive theA same. The refrigerant from thecompressor is adapted to be discharged from the compressor 9 throughdcnserlO within the base l. The refrigerant is permitted to How throughthe pipes of the condenser 10 to be cooled and condensed beforev beingreturned to the compressor.

As illustrated in Figure 1 the fan 8 is mounted on the motor shaft?between the motor and the compressor and when operated by the motorshaft 7 acts to draw air upwardly through the open bottom of the base 1to first cool' the condenser 10 after which the air is drawn upwardlyinto the hood 5 and is discharged through the mouth or opening G againstthe compressor 9 to cool the same. 'lhe baffle wall or plate 12 withinthe base 1 acts ,to direct the flow of air upwardly from the base intothe hoodV 5. 1t will thus be seen that the fans 8 is adapted to causeair to flow upwardly through the base 1 and through the hood 5 to causecooling of both the condenser 10 and the compressor 9 by a very simplearrangement.

We are aware that many changes may be made4 and numerous details `ofconstruction f may be varied through a widerange without departing fromthe. principles of this invention, and we therefore do not purposelimiting the patent granted hereon other- Wise than necessitated by theprior art.

We claim as our invention: p

1. In a refrigerating unit comprising` a base open at the bottom andhaving'an opening in the top thereof, a condenser mounted in said base,a hood mounted on said base over the opening in the top thereof, a motormounted on said base, a compressor on-said base connected with saidcondenser, a shaft connecting the motor' with .the compressor andprojecting through said hood, and a fan on said shaft within said hoo-dadapted to draw air upwardly through the base to cool the condenser andthen direct the air against the compressor to cool thesame.

2. A refrigerating unit comprising a base,

a condenser therein, a motor and a compres sor mounted on said base, ahood mounted on said base between the motor and compressor, said hoodhaving an `opening in the bottom thereof communicating with the interiorof the base, a second opening in the wall thereof adjacent saidcompressor,` a shaft driven by said motor projecting through the hoodand connected to drive the compressor, and a fan within said hoodmounted on the shaft to be rotated thereby to cause air to be drawnupwardly through the base to cool the condenser and furthermore adaptedto direct air drawn into the hood against the compressor to cool thesame,

3. A refrigerating unit comprising a hollow base open at the bottom andlhaving an openin in the top thereof, a hood mounted on sai base abovethe top opening, said hood having an opening therein, a condensermounted in said base, a compressor and a motor mounted on said base onopposite sides of said hood, a shaft projecting through said hood andconnecting said mot/or with said compressor, means for connecting saidcompressor with said condenser, and a cooling device mounted in saidbood adapted to be operated by said shaft to cause air to be drawnthrough the base to cool the condenser and discharged through theopening in said hood to cool the compressor.

4. In a refrigeratingunit the combination with a base-having an openingtherein, of acondenser mounted thereingofI a hood mounted on saidr baseand registeringwith said opening, a shaft in said hood, va motor mountedon said base adapted to drive saidA shaft, and a fan infsaid hoodmounted on said shaft adapted when operating to cause air to be drawnupwardly through the base to cool the condenser.

5. A refrigerating unit comprising a base having. an opening therein, avcondenser mounted therein, a compressor mounted on said base, a fan onsaid base above said opening, and a driving means for said compressoradapted to operate the fan to cause .cooling of the condenser and saidcompressor. A p

6. In a refrigerating unit, a base having an opening in the bottomthereof, a radiator type condenser withinsaid base, a compressor mountedon said base, and means for drawing air through said condenser anddirecting the air against said compressor for cooling the condenser andcompressor.

7. In a refrigerating unit, a supporting base having an open bottom, acondenser within said base enclosed by the Walls and top thereof, acompressor mounted on the top of said base, means for drawing air pastthe condenser and through an opening in the top ofy thebas'e, and meansfor directing the air so drawn through the base onto the compressor. Intestimony whereof we have Ahereunto subscribed our names.
